- /**
- * C API representing a collection of resource information pertaining to a given
- * locale. A resource bundle provides a way of accessing locale- specific information in
- * a data file. You create a resource bundle that manages the resources for a given
- * locale and then ask it for individual resources.
- * <P>
- * The resource bundle file is a text (ASCII or Unicode) file with the format:
- * <pre>
- * . locale {
- * . tag1 {...}
- * . tag2 {...}
- * . }
- * </pre>
- * The tags are used to retrieve the data later. You may not have multiple instances of
- * the same tag.
- * <P>
- * Four data types are supported. These are solitary strings, comma-delimited lists of
- * strings, 2-dimensional arrays of strings, and tagged lists of strings.
- * <P>
- * Note that all data is textual. Adjacent strings are merged by the low-level
- * tokenizer, so that the following effects occur: foo bar, baz // 2 elements, "foo
- * bar", and "baz" "foo" "bar", baz // 2 elements, "foobar", and "baz" Note that a
- * single intervening space is added between merged strings, unless they are both double
- * quoted. This extends to more than two strings in a row.
- * <P>
- * Whitespace is ignored, as in a C source file.
- * <P>
- * Solitary strings have the format:
- * <pre>
- * . Tag { Data }
- * </pre>
- * This is indistinguishable from a comma-delimited list with only one element, and in
- * fact may be retrieved as such (as an array, or as element 0 or an array).
- * <P>
- * Comma-delimited lists have the format:
- * <pre>
- * . Tag { Data, Data, Data }
- * </pre>
- * Parsing is lenient; a final string, after the last element, is allowed.
- * <P>
- * Tagged lists have the format:
- * <pre>
- * . Tag { Subtag { Data } Subtag {Data} }
- * </pre>
- * Data is retrieved by specifying the subtag.
- * <P>
- * Two-dimensional arrays have the format:
- * <pre>
- * . TwoD {
- * . { r1c1, r1c2, ..., r1cm },
- * . { r2c1, r2c2, ..., r2cm },
- * . ...
- * . { rnc1, rnc2, ..., rncm }
- * . }
- * </pre>
- * where n is the number of rows, and m is the number of columns. Parsing is lenient (as
- * in other data types). A final comma is always allowed after the last element; either
- * the last string in a row, or the last row itself. Furthermore, since there is no
- * ambiguity, the commas between the rows are entirely optional. (However, if a comma is
- * present, there can only be one comma, no more.) It is possible to have zero columns,
- * as follows:
- * <pre>
- * . Odd { {} {} {} } // 3 x 0 array
- * </pre>
- * But it is impossible to have zero rows. The smallest array is thus a 1 x 0 array,
- * which looks like this:
- * <pre>
- * . Smallest { {} } // 1 x 0 array
- * </pre>
- * The array must be strictly rectangular; that is, each row must have the same number
- * of elements.
- * <P>
- * This is an example for using a possible custom resource:
- * <pre>
- * . const char *currentLocale;
- * . UErrorCode success = U_ZERO_ERROR;
- * . UResourceBundle* myResources=ures_open("MyResources", currentLocale, &success );
- * .
- * . UChar *button1Title, *button2Title;
- * . button1Title= ures_get(myResources, "OkKey", &success );
- * . button2Title= ures_get(myResources, "CancelKey", &success );
- * </pre>
